每当我尝试启动我的 Web 应用程序时，我都会收到此类型错误。无法弄清楚原因。

我在更新一些软件包后开始遇到此问题。我无法弄清楚哪一个是问题所在，也无法弄清楚错误指向的代码为什么会出错，因为它是我的 Angular 8 依赖项中的代码。我甚至不确定错误到底在告诉我什么。 我尝试更新所有依赖项。我查看了几乎所有类似的问题解决方案，但都没有奏效。我不知道这是编译器错误、typescript 还是依赖项错误。

错误

        __extends = function (d, b) { 
            extendStatics(d, b); *//saying the error is coming from here*
            function __() { this.constructor = d; }
            d.prototype = b === null ? Object.create(b) : (__.prototype = b.prototype, new __());
        };

我期望应用程序能够编译、构建和启动。每当我尝试 ng serve、ng test 或 ng build 时，我都会收到此错误。
